论文摘要
我们分析了具有超对称性的无尺度SU（5）模型中的杂种膨胀，这自然会绕过单极问题。无尺度的框架是弦理论的超对称（SUSY）压缩的有效田间理论，它产生平坦的电位，而没有抗DE保姆真空吸尘器，从而解决了$η$问题。该模型预测标量光谱tilt $ n_s $与普朗克卫星的最新测量兼容，同时还可以容纳可观察到的张量与标准比$ r $ $ r $（$ \ sim 0.0015 $）的可观察值，这可能是可通过近场实验来测量的。此外，发现在尺寸5算子存在下的质子衰变寿命超过了超级kamiokande实验所施加的当前极限。调用了重新加热和非热卵生成的现实情况，其中重新加热的温度$ t_r $位于$ \ {2 \ {2 \ times 10^6 \ sillssim t_r t_r \ sillsim t_r \ sillsim 2 \ lyssim 2 \ times 10^9 \} $ gev范围，以及同一时间的gravitino canditiation the cable canditaide cand（dm）cand（dm）。
We analyse the shifted hybrid inflation in a no-scale SU(5) model with supersymmetry, which naturally circumvents the monopole problem. The no-scale framework is derivable as the effective field theory of the supersymmetric (SUSY) compactifications of string theory, and it yields a flat potential with no anti-de Sitter vacua, resolving the $η$ problem. The model predicts a scalar spectral tilt $n_s$ compatible with the most recent measurements by the Planck satellite, while also accommodating observable values of the tensor-to-scalar ratio $r$ ($\sim 0.0015$), potentially measurable by the near-future experiments. Moreover, the proton decay lifetime in the presence of the dimension-5 operators is found to lie above the current limit imposed by the Super-Kamiokande experiment. A realistic scenario of reheating and non-thermal leptogenesis is invoked, wherein the reheating temperature $T_r$ lies in the $\{2 \times 10^6 \lesssim T_r \lesssim 2 \times 10^9\}$ GeV range, and at the same time the gravitino makes a viable dark matter (DM) candidate.
